In picking Sen. Joe Biden to be his running mate, Barack Obama sought to shore up his weakness — inexperience in office and on foreign policy — rather than underscore his strength as a new-generation candidate defying political conventions.

The Obama campaign’s 3 a.m. text message meant that supporters who signed up to be the “first to know” instead received the news from old media.

The early morning announcement was too clever by half. While Obama's supporters were sleeping, the McCain campaign was rolling out a TV ad that features Biden saying that Obama is not ready to lead.

When folks read their text message or email, it wasn't an OMG moment. According to a Washington Post-ABC News poll, 75 percent of voters said picking Biden would not make a difference one way or the other.

Joe Biden. OK, whatever. It’s time to go for my morning walk, grab a cup of coffee and run some errands.
